Fibonacci Numbers in Flowers!

Why is it that the number of petals in a flower is often associated with one of the following numbers: 3, 5, 8, 13, 21, or 34? Read on to explore the answer.

Have you heard about the famous Italian mathematician Leonardo Fibonacci and his Fibonacci number series given by the infinite elements: 0,1,1, 2,3,5,8,13,21,34,55,…;? Nature, in particular plants, have no foreknowledge of this number sequence, but surprisingly, majority if not all petal arrangement of flowers carry these numbers!Below are some flowers that follow the Fibonacci number series.

    Wow… you’re a genius Sir Papz, I never thought of relating Fibonacci numbers to the petals of flowers. And now that you mentioned it, it really got me wondering too. God really made nature with mysteries.

    The flowers are so beautiful… Tamang-tama for Flores de Mayo.
    Excellent share Sir Papz..

    I first came across Fibonacci numbers in Dan Brown’s book. Later I found out this number sequence is not only seen in nature but is also used as a statistical tool in the stock market. Really fascinating and brilliant observation by Fibonacci.
